MACHINE FOR SKIVING HEEL-LIFTS.

SPECIFICATION forming part of Letters Patent No. 462,594, dated November 3, 1891.

Application filed July 2, 1891.

T0 @ZZ whom. t may concern:

Be it known that I, JACOB R. SCOTT, a citizen of the United States, residing at New York, in the county and State of New York, have invented new and useful Improvements in Skiving-llIachines, of which the following is a specification.

This invention relates to certain improvements in skiving-machines, as pointed out in the following specification and claims, and illustrated in the accompanying drawings, in which Figure 1 represents a transverse vertical section in the plane s s, Fig. 2. Fig. 2 is a side elevation, partly in section. Fig. 3 is a transverse vertical section in the plane t t, Fig. 2. Fig. a is a plan or top view. Figs. 5 to S, inclusive, are elevations of dies which may be used in my machine. y Fig. 9 is a longitudinal section of one of the dies in the plane u u, Figs. 5 and G. Fig. 10 is a partial section in the plane u r, Fig. 6. Fig. 11 is a longitudinal section in the plane w tu, Figs. 7 and S. Fig. 12 is a partial section in the plane :r fr, Fig. 3. Fig. 13 is a face View of a lift for boot and shoe heels produced on my machine. Fig. 13 is a longitudinal section of a blank for a lift, showing the line of the cut. Fig. 14 is a transverse section in the plane y y, Fig. 13.' Fig. 15 is a face view of an insole produced on my machine. Fig. 16 is a transverse section in the plane z, Fig. 15. Fig. 17 is a similar section in the plane e z', Fig. 15.

In the drawings, the letter A designates the bed-plate, from which rise two standards I3 B, which form the bearings for the shaft C.

On this shaft is iirmly mounted the roller D,

which contains the half-die cavities d, and said shaft C is geared by cog-wheels a a with a counter-shaft C, which carries the roller D and which has its bea-rings in two arms E E, which extend from a hub F, situated between the standards B I5, Fig. 4, and mounted upon a rod G, supported in said standards. The front ends of the arms E E are exposed to the action of springs h l), which have a tendency to force the roller D up in contact with the roller D. From the hub F extends an arm e, which carries a screw f for regulating the distance between the rollers D D. If this screw Serial No. 398,269. (No model.)

is screwed in, the arms E E are depressed and the roller D is prevented from risi ng up in close contact with the roller D. The roller D` contains the half-die cavities d', which co-operate with the half-die cavities d in the roller D. For instance, in order to produce l-ifts for boot and shoe heels (see Figs. 13 and 14) the roller D is provided with a die-cavity d, Figs. 5 and 9, the contours of which conform to the lift and the bottom of which is convex, Fig. 9, so as to force the blankinto Aa die-cavity d formed in the roller D,Figs. 7 and 11. Then a blank is placed into the die-cavities d d and 'the rollers D D are caused to revolve in the direction of the arrows marked thereon in Fig. 1, the blank is brought in contact with a leather splitting or dividing knife II, Figs. 1 and 4, and those portions of the blank which project beyond the surface of the roller D are cut away, so that by each revolution of the rollers D D a lift for a boot or shoe heel or any other article of a similar nature can be produced. For instance, in Figs. 15, 16, and 17 I have shown the insole for a boot or shoe, and in Figs. G, S, 10,and12 I have shown the dies do do in the rollers D D, which are required in order to produce such insole from a suitable blank.

In Fig. 13 I have shown a sect-ion of the blank for forming a lift for boot and shoe heels. This blank lits the die-cavity d of the roller D, Figs. 5 and 9, and this die-cavity is of such a depth that when the blank is placed into it the portion zo, Fig. 13, projects beyond the surface ofthe roller D, and a portion of said projecting portion enters the die-cavity d in the roller D', Figs. 7 and 11. As the rollers revolve, the blank is split in the line 1 2, Fig. 13, and a lift is formed, such as shown in Figs. 13 and 1l, while the portion n; of the blank is waste. The knife II extends between the rollers D D', as shown in Fig. 1,

wheel extends into a clutch M, which is firmly mounted on the shaft C and which carries a and it may be firmly secured to a bracket h,

lOO

dog m, which, when free to follow the action of a spring n, Fig. 3, engages atooth Z, formed on the hub of the cog-wheel L. When the dog m is in engagement with this tooth,l the cog-wheel M is thrown in gear with the shaft C and the rollers D D are set in motion. The dog m can be thrown out of gear with the hub of the cog-Wheel L by any suitable means-such, for instance, as a bell-crank lever N, which connects by a rod O, Fig. 3, with a treadle, (not shown,) so that whenever said rod is forced downward the dog m is thrown out of gear with the hub of the cogwheel L and the movement of the rollers D D is stopped, and when the rod O is free to follow the action. of the spring o the dog m is thrown in gear with the cog-wheel L and the rollers D D are setin motion.

That I claim as new, and desire to secure by Letters Patent, is-

l. In a skiving-machine, the combination of the drive-shaft I, the counter-shaft C, having a gear a and carrying the lower die-roller D', the shaft C, gearedto the drive-shaft, provided with the upper die-roller D, and having a gear a engagingthe gear of the countershaft, the rod G, the hub F, arranged on the rod and having the arms E, carrying the counter-shaft, and the arms e, provided with a' set-screw f, the springs b, located beneath the arms which support the counter-shaft for pressing the lower die-roller upwardly against the upper die-roller, and the knife I-I, extending between the two die-rollers, substantially as described.

2. In a skiVing-machine, the combination, with the knife H, the shafts C C', and the dierollers DD', mounted thereon, of the drivingshaft I, the cog-Wheel L, mounted loosely on the shaft C and geared with the driving-shaft, the clutch M, mounted firmly on the shaft C and carrying the spring-actuated dog m, a tooth Z, formed on thehub of the cog-Wheel L in position 4to engage the dog m, and means for throwing the dog out of gear with the cogwheel, substantiall;7 as described.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.

A JACOB R.A SCOTT.
